.3. One day you happen to hear a snippet of conversation between two graduate students, who are drinking coffee and contemplating an open box of exquisitely delicious chocolate truffles in the Page Break Café.

The second student disagrees vehemently and argues that the one and only important thing to worry about is aesthetics. The first student is speechless. What do you think? Use your knowledge of data visualization to inform your answer, and be sure to explain your answer carefully.
